Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a detachable in-ear headphone. Background Technology

[0002] The headphones include a shell and a driver unit housed within the shell. The driver unit includes a magnetic circuit assembly and a vibration assembly. The voice coil in the vibration assembly is connected to an external power source via a voice coil lead. When energized, the voice coil vibrates in the magnetic field of the magnetic circuit system. The vibration of the voice coil drives the diaphragm to vibrate, thereby resonating with the surrounding air to produce sound. In-ear headphones are perfectly coupled to the outer ear canal of the human ear, resulting in high sensitivity and physical noise reduction. Existing headphones are divided into wired and wireless types. The driver unit of wired headphones is connected to a connector via a connecting cable. The connector is then connected to an external device to transmit the audio signal output by the external device to the driver unit for sound production. Wireless headphones, such as Bluetooth headphones, communicate with external devices via wireless signals such as Bluetooth signals.

[0003] Wired headphones suffer from drawbacks such as the inconvenience of the wiring and poor contact at the connectors after repeated plugging and unplugging. While wireless headphones eliminate the need for wiring, they require charging, limiting their continuous use. To combine the advantages of both, some manufacturers produce separate headphones that allow for switching between wired and wireless communication. For example, Chinese Patent Publication No. CN205693849U discloses a "separate headphone and its sound-producing part, wireless signal part, and wired signal part." The sound-producing part plays audio through the left and right sound units. The wireless signal part communicates wirelessly with external devices via a wireless communication module. The wired signal part connects to the data interface of an external device via a connector for wired communication. The sound-producing part can be connected to either the wireless or wired signal part independently. Therefore, this separate headphone allows for switching between wireless and wired communication with external devices by replacing either the wireless or wired signal part.

[0004] However, in actual use, when using the wired signal unit to communicate with external devices, the first magnetic attraction part and the third magnetic attraction part are magnetically connected. When the user is in motion, poor contact may occur between the audio channel contacts. During strenuous exercise such as running or jumping rope, the first magnetic attraction part and the third magnetic attraction part may even separate and fall off, affecting the user experience. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as poor contact in magnetic connections, and the possibility that the first magnetic attraction part and the third magnetic attraction part may separate and detach during vigorous exercise, affecting the user experience. Therefore, this invention proposes a detachable in-ear headphone.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a detachable in-ear headphone, including a connecting cable, with connectors and plugs at both ends of the connecting cable, a battery inside the connector, a circuit board inside the connector, a volume control button on the connector, and two output lines on the connector that are connected to the circuit board. The output lines pass through the connector and are connected to the headphone head. The connector and the connecting cable are connected by a connecting structure.

[0008] Furthermore, the connection structure includes a connecting cylinder, which is fixedly disposed on one side of the connector, and the connecting line is provided with a connector head that mates with the connecting cylinder.

[0009] Furthermore, a connecting cover with internal threads is fixedly provided on the connecting head, and the connecting cover is threadedly connected to the connecting cylinder.

[0010] Furthermore, the connecting cylinder has an installation hole, an installation part is provided in the installation hole, and a conductive column that cooperates with the installation part is fixedly provided on the connecting head.

[0011] Furthermore, multiple insulating steps are fixedly provided on the mounting part, and each insulating step is provided with a conductive part, which is connected to the conductive post.

[0012] Furthermore, a spring is fixedly provided on one side of the mounting part, and the other end of the spring is fixedly connected to the mounting hole.

[0013] Furthermore, an elastic band is fixedly provided on one side of the connector, and a dust cap that cooperates with the connecting cylinder is fixedly connected to the elastic band.

[0014] The detachable in-ear headphones proposed in this utility model have the following advantages:

[0015] In this invention, the connector and the connecting wire are connected by a connection structure, and the connection method is a threaded connection, which is more secure and stable than a magnetic connection, and effectively avoids poor contact and detachment.

[0016] Secondly, in this invention, by setting a spring to cooperate with the mounting part, the spring presses the mounting part against the conductive post of the connector in place, thereby tightly abutting the conductive part against the conductive post, preventing the conductive part and the conductive post from being unable to contact each other after wear, and increasing the service life of the headphones.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A detachable in-ear headphone includes a connecting cable 1, with connectors 2 and plugs 3 at both ends of the connecting cable 1. A circuit board is disposed inside the connector 2, and a volume control button is disposed on the connector 2. Two output lines 4 are disposed on the connector 2 and connected to the circuit board. The output lines 4 pass through the connector 2 and are connected to the headphone head 5. The connector 2 and the connecting cable 1 are connected by a connecting structure 6.

[0024] In this invention, the connector 2 and the connecting line 1 are connected by a connecting structure 6, which is more secure and stable than magnetic connection, effectively avoiding poor contact and detachment. In some embodiments, the connector 2 is equipped with a battery and a Bluetooth module, which can be connected to a mobile phone via Bluetooth module, or the connector 2 can be connected to a Bluetooth wireless connection device to connect to a mobile phone via Bluetooth wireless connection device.

[0025] Furthermore, in this embodiment, the connecting structure 6 includes a connecting cylinder 61, which is fixedly disposed on one side of the connector 2. The connecting line 1 is provided with a connector head 62 that cooperates with the connecting cylinder 61. The connector head 62 is provided with multiple grooves to increase the contact area of ​​the connector head 62 and improve the friction to facilitate the rotation of the connector head 62.

[0026] Furthermore, in this embodiment, a connecting cover 63 with internal threads is fixedly provided on the connector 62, and an external thread is provided on the outer wall of the connecting cylinder 61. The connecting cover 63 is threadedly connected to the connecting cylinder 61. The threaded connection has self-locking properties and is more secure and stable than the magnetic connection.

[0027] It should be noted that, in this embodiment, the connecting cylinder 61 is provided with an installation hole, and an installation part 64 is provided in the installation hole. A transmission post 65 that cooperates with the installation part 64 is fixedly provided on the connector 62. The transmission post 65 is electrically connected to the connecting line 1. The transmission post 65 is provided with multiple protruding contact parts, which are insulated from each other, and electrical signals are transmitted by multiple contacts.

[0028] Furthermore, in this embodiment, a plurality of insulating steps 66 are fixedly provided on the mounting part 64. The heights of the plurality of insulating steps 66 are different and correspond to the protruding contact parts on the conductive post 65. Each insulating step 66 is provided with a conductive part 67, which is electrically connected to the connector 2. The conductive parts 67 are all connected to the conductive post 65. The conductive parts 67 are insulated from each other to prevent interference.

[0029] In detail, in this embodiment, a spring 68 is fixedly provided on one side of the mounting part 64, and the other end of the spring 68 is fixedly connected to the mounting hole. The spring 68 presses the mounting part 64 against the conductive post 65 of the connector 62 that is installed in place, thereby tightly abutting the conductive part 67 against the conductive post 65. Even if the conductive part 67 and the conductive post 65 are partially worn, the effect of contact and signal transmission will not be affected, thus increasing the service life of the headphones.

[0030] More specifically, in this embodiment, an elastic band 7 is fixedly provided on one side of the connector 2, and a rubber dust cap that cooperates with the connecting cylinder 61 is fixedly connected to the elastic band 7. When the connector 2 is equipped with a battery and a Bluetooth module and is connected by a wireless Bluetooth module, the dust cap can be connected to the connecting cylinder 61 to prevent dust and sweat from entering the connecting cylinder 61.

[0031] Working method: During operation, the connecting cover 63 of the connecting cylinder 61 is threadedly connected to the connecting cylinder 61. The threaded connection has self-locking properties. After the connecting cylinder 61 is installed in place, multiple insulating steps 66 are connected to the conductive post 65 to form an electrical connection to transmit signals. The spring 68 presses the mounting part 64 to abut against the conductive post 65 of the installed connector 62, thereby tightly abutting the conductive part 67 against the conductive post 65.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
